Foundation and Member States
The Organisation for Economic Co-operation and Development (OECD) is an international intergovernmental organisation. It finds its origin in the Organisation for European Economic Cooperation (OEEC) of 1948, created to administer the Marshall Plan aid provided by the USA and Canada for the reconstruction of Europe after the Second World War. By successfully achieving that governments recognized the interdependence of their economies, the foundation for a new era of cooperation was laid and started the change of Europe's image. Encouraged by their success and the prospect of advancing their work globally, the United States and Canada joined the OEEC members in signing the new OECD Convention on 14 December 1960. The Organisation for Economic Co-operation and Development (OECD) was officially born on 30 September 1961, when the Convention entered into force by establishing its headquarters in Paris.
 
 
 
The Organisation is open and allows third countries to participate in its committees, working groups and fora. This participation is regulated and established under three categories: guests, participants and associates according to the degree of minor to greater implication and with the payment of quotas in the last two cases.
 
Currently, there are 37 OECD member countries, 20 of which are founders - Spain among them - and the rest have been incorporated successively starting with Japan (1964), Finland (1969), Australia (1971), New Zealand (1973), Mexico (1994), Czech Republic (1995), Korea, Hungary and Poland (1996), the Slovak Republic (2000), Chile, Estonia, Slovenia and Israel (2010), Latvia (2016), Lithuania and Colombia (2018). The EU has an observer status in the Council with the possibility to speak but does not hold any voting powers.

In addition to OECD member states, 11 non-member countries have signed up to the implementation of the OECD Guidelines: Argentina, Brazil, Costa Rica, Egypt, Jordan, Morocco, Peru, Romania and Tunisia.  Moreover, the OECD holds a closer and more privileged relationship with the so-called Key Partners (Brazil, China, India, Indonesia and South Africa) who even participate in Ministerial Meetings.
